New features in 22.04 LTS
Ubuntu 22.04 LTS ships multiple optimized kernels on per-product basis:
- Ubuntu Desktop will automatically opt-into v5.17 kernel on the latest generations of certified devices (
- Ubuntu Desktop uses a rolling HWE kernel (
linux-hwe-22.04) on all other generations of hardware. The rolling HWE kernel is based on the v5.15 kernel for 22.04.0 and 22.04.1 point releases
- Ubuntu Server defaults to a non-rolling LTS kernel v5.15 (
Additional optimized and certified kernel flavours will become available in Ubuntu 22.04 LTS in due course.

- Dock devices and filemanager integration has been improved

- GNOME Shell and mutter have lots of performance improvements including the triple buffering patch.

- RDP is now available for sharing your desktop remotely. Legacy VNC is still available, but it is strongly recommended to use RDP for better security, privacy, and performance.
